To all Awhom it may concern:

Be it known that I, JAMES D.. DAUGHERTY, a citizen Oi the United States, residing at Kittanning, inthe county of Armstrong and State of Pennsylvania, have 5 invented e. new and useful Computing Mechanism, Oi which the following is e. specification. This invention relates to computing mechanism especially adapted for luse as a part of the organization of a. combined typewriting and adding machine disclosed in my copending applicationior Letters Patent led May 10,1901, Serial Number 59,631, of which the present application is it division. v f

The invention is directed provenient of that part oi the machine organization which is known in the art as the register or totalizer, which, in the present instance, embraces a series of denominationol'members O r number Wheels, transfer mechanism by means oi which the limitiol value accumulated upon4 one wheel is automatically transferred to for the Wheels and transfer mechanism respectively, :md locking mechanism -ior the wheels` The objects oi" the invention are to provide simple and chlcient locking mechanism lor preventing premature or accidental movement of the number wheels; to provide said 4 wheels 1with transfer. mechanism which, while controlled by the wheels, is Operated by transfer motors which relieve the primary operating mechanism ofthe burden ordinarily ini-posed upon it by the carryin'g'oporation; to-provi'de moons common to allot the .carrying devices iol-returning them to normall position' and iorrestoring the-energy expended byA the transfer '1110tors; and to provide a simple and positively operating form oi wheel resetting"mechanism by means oi zWhich the wheels may be quickly and convenientlylresetjto Zcroupon the completion of -a given computation. l

Since the mechanism embodying the vpresent inventiert-has been designed with spor-inl rci'erence to its use in connection with a typewriter, 1 have illustrated suid machine, although it should be understood that the computing mechanism per se is the only structure 1 claimed herein nndtlntt it is useful in many relations I other than that which has been selected iur illustrative purpses. v

1 indicates the framp of the tylnzwriter, 2 the traveling ciu'ringc thereof, which is power driven and escapemcnt controlled, ns usual, 3 the numeral keys, i the numeral key levers, and 5 the lutter key levers. The computing device casing G is attached to the right hund 9 5 side of the typewriter .frame and' incluses the computing mechanism, with which the present invention is concerned. This computing mechanism includes a series oi' nine'denominational members in theiorm of wheels a, b, c, d, c,f, y, h, and i', representing different denominational values, as lor instance, units, tens, hundreds, thousands, tens of thousands, hundreds of thousands, millions, tens oimillions, und hundreds o' mil' lions; or, if. money values are computed, the two wheels I 1 'of lowest denomination may represent units and tens of 5 .A .wheel-in the present embodiment of the invention is provided 'with thirty teeth, bearing three series of digits each-ranging fromV Q O" to 9 inclusive, one digit on each wheelbeing eihibitd oppositea sight opening 14 in the casing 6. The several number Wheels a, b, etc.,`are designed to be presented successively in coperative relation with an actuator or master wheel 15 during the movementof the. computing carriage upon the 'tracks 9 and 10, said carriage being lnormally located at theext-reme right hand side of the casing 6 so that the number wheel 1l of highest order will be to .the right of and out of engagement with the actuator l5, as shown in Fig. 4. p

The advance of the computing carriage to the left to present the number wheel of highest order and there after successive number wheels opposite the master wheelor actuator 15 is eHected by the propelling mechi p anism ofthe typewriter carriage bearings adjacentfto the'rear side of the 2 through the medium ofthe latter. The particular means whereby this end is attained constitutes no part of however, and it is therefore deemed to be sulcient'to state that it includjes a rock shaft '17 mounted in suitable typewriter and provided at its spper and lower ends with forwardly extending arms il andU 18 respectively, the latter havf ing a vertically disposedextremity l19 iconnected by a 'link 20 to the computing carriage 8, see Figs. 1 and 4,

and the former, to-wit, the arm 21, having a vertically disposed extremity 2 2 arranged to be engaged by pro- -jections 23 ontlie typewriter-carriage. As the typewriter earria'ge moves to the left during the operation of i I printing digits in the column to -be computed, the shaft A presented- .printing point of the' machine.

17 willbe rocked to advance the computing carriage 8 cause' the number wheels to. be successively to the actuator Vl5, as the denominational poare successively presented to 'the In a similar manner and thus/ sitions of the.column the retraction of the typewriter carriage 4effects the re;

`"fnumeral keys-3 ofthe typewriter,

. proportionate tothe value of: the

tract'iinof the computing carriage 8. It may also be stated, in a general way, Ithat the actuator 15 is mounted in a shaft 27 driven by a motor and 'controlled by the v so that, upon the depression of a key, the master wheel lwill be permitted to rotate, under the impulse of the motor 428, a distance pressed, a corresponding rotary movement being thus keys, "but attentionmay be directed to the' fact thatl imparted to thatnumber wheel which correspondsin denominational Vposition to the ordery or denomina'- tionalposition in which the digit is'printed infthe solemn en worksheet. I'

It is unnecessary to describe in detail the mchamism whereby the master wheel 'is controlled-from the fol` nine increments or units my present invention,

particular key riethis mechanism includes a detent 45 normally engaging and' holding the master wheel and arranged 4to be withdrawn therefrom by a bail 48 disposedor operation by any one of the several numeral key levers, see particularly Fig. 9. i The carrying ortrnfer mechanism. Coming now to the subject-matter hereinafter claimed, it is in order to 'describe the mechanism for locking the number wheels against accidental movement and for automatically imparting a single increment of movement to a given 'wheel as the wheel of next lower order moves from 9 to Oi As is well understood in the art, this mechanism is designed to transfer to a wheel of higher denomination the amount accumulated upon a wheel of lower order when such amount reaches the limit of. denominational value of the Wheel last-named. Thus the denominational value of each wheel being 10, .it

will rotate independently of the wheels of higher order of'movement, the digits l, 2, 3, 4, 5, 6, 7', 8 and 9 being successively exhibited before the sight opening` The nextl or tenth increment will be the limit of denominationalv value, and therefore, as this movement is effected to present .0 at

the sight opening, asingle increment of movement willl be imparted to the wheel -of nexthigher order or de: nomination, thus causing the latterto exhibit, forinf.

stance, the numeral 1, which will be the equivalent v of the ten increments accumulated by the lower wheel.

. Each number wheel, except the wheel of highest order, isrequipped on the -left hand side face thereof' with three small segmental trip levers 74, sec Fig. 8, fulcrumed intermediate of their ends and associated each with a stop pin which-limits the swinging mover ment of the lever in one direction. The trip levers 74 coperate with `earn lugs or projections 76 extendingfrom the peripheri'es of a series of resetting cams ordisks 77, mounted onth'e number wheel shaft 7 andalt'erna't ing with the number wheels, 4.

disks 77 is'appropriated to each wheel, of highest order, and is 'equipped with j ections 76 each of which cooperates with a tn'p lever 74 in the 4resetting operation, to be presently described.

except the wheel It' will be understood thateach wheel is equipped with i three of thev levers 74 4for-the reason that the wheel has thirty. teeth and must', therefore, operate three times lin each complete rotation thereof for the purpose-of Thus one of these Ythr'ee of the procausing the advance of the nexti'higher wheel` So far as this carrying or transferring function is concerned',

- however, only one oi the cam projections 76 is ol'ective,

the uppermost projection in Fig. 8 serving to swing each of the lever 374 in'succession as they ride over said projection, and the otlier two projections 7 in said figure having no special utility so far as the carrying opemtionis concerned.

n'ang'ed to cooperate with levers 7,4 are e series of-locking pivoted upon ashaft 79 extending acrossthe computing carriage 8, Figs. 2,- 5 and 6. These -locking armsjlv efx'tend forwardly from the shaft 79 arideach urged downwardly by a spring 80 secured to bar-8L Miha front endl of each arm 78 is-,formedy a curved.beak or projectign 82 disposed to cooperate with the trip levers '771. `Opposite the adjacent the severallscts of i 'arms 78 independently wheel :and inirear of the v beak, each-arm is formedj 'with a locking lug 83, which,

in the normal position of the arm, shown in Fig. 5, extends behind the speer-shaped hes-d 84 of a transfer member 85, oneof these transfer members being prvided for each wheel, except the wheel uf lowest order '5 or denomination; The head of each' transfer member 85 normally rests upon a. tooth of n. number wheel, the outer faces oi' the teeth beingr inclined, es shown, so as to permit the headof thmtransfer member to d rop down in front of the tooth in rear ofthe one nponwhieh the l0 hendi'estsl- Attention is directed to the feet th-.tt by the described arrngement of parts, e-.u-h locking' arm '7S is 4arilenged to cooper-.ite with u set of trip levers 74 mounteden one wheel, and locks against resrwnrdmovement4 'mtrttnsfer' member 85., the head of which is hooked over 2. tooth of the number Wheel of next higherl order.

l.secured the front end of s-spring 88 having its rea-rend.

'xlsecured o a. bar 89 on the carriage 8. The several 'springs l823 constitute. independent transfer motors, since 'each spring exertsa constant tendency to retract f l .a transfer member 85 and to thus imp-srt a single increbnent oi' movement to the number wheel engaged by said member. This operation ol' the transfer. member .is normally prevented, however, bythe locking'arm 78 and' isnot permittted until the next lowernumber Wheel, having completed nine increments of independent movement, presents s, trip lever 74 to a lug 76 during -its next or tenth increment of movement `.rnd thus causes said trip lever to swingr on its pivot and engage l sind elevatethc front end of the locking' ztrm 78, thereby ,3 5;.wi1hdrayving the locking lugY SS from behind the head of the trmisfer member 8 und releasing the latter to permit it to impart it single increment of movement to the Y next higher number wheel under the impulse oi the mo.

tor spring 88, see Figs. 5 and o'.

Thaptca'rtsfor locking hr number 'what-ls rifle-r carrying. lt is desirable to utilize the transfer mechanism to' securely lock the it'heels aller the sume have been cnr-` ried, and it will btl understood thru. no wheel will be carried, that is to srry', no numberwheel n'ill bc cnused to vv't5 rotated-)y another number wheel until 'the i'ormer hns moved lo the left ol' the-actuator l5, since smid ztctnntt'xr constitutes the 'prime lmover ol' thc computingr device, and itis therefore impossible to release the curi-ying mechanism ol" tiny wheel unless it is located lo the left v y o flhc one in engagen'i'ent with the actuator.

Extending across the casing (3 isn. lockingr bnr 90, therig-lrt hund hull' ofwhch is cut rtw-ny, as ind-cated in liigs flztnd '7, so th-.tt its effective portion is located to the. left of the actuator l5, er, in other words, opposite l 55 thmwheels which inztybe to the left ofthe ncl-unter lnd therefore inposition to be carried. The bnr llt) is zirrtniged lo be eng-'aged by 1t projet-tion i-)l formed un erich tiitnsler member, and serves yto prevent the letter from v nll og back toe far and also retains the member se- .tltl curelvin engttgement with the carried wheel, thus preven ng the overthrow of the latter in either direction. In this, the retracted position ofthe transfer member, shown in Fig.- 6, the projection 83 on the locking :trn1'7lA restsupon the'heacl 84 of thetransi'er member 85 and as# by the locking bei' 90 and the stop bar 8 7 sind that its forward movement is resisted by the locking erm 78.

inasmuch, however, as it is desired Ito positively lock the transfer member against forward as well as backward' movement, after it has been operated, I provide a series of pivoted locking dogs 92 hung from a rod 93 extending across the-casing G above the transfer members.4 These dogs 92 extend rearwardly over the barvQO arid their extremities rre normally located behind loe-king lugs 9'4'0n the transfer members 85, as shown in Fig. When, however, the trad-sier member is retracted in the act of carrying, the lug 94 lifts the dog 92,-and the letter subsequently drops down in vadvance of the lug, as shown in Fig. (i, and thus positively prevents accidental forward movement of the transfer member.

As shown in Figs. 2 and 4, the locking dogs'92 are located to the left of the actuator l5, one dog being .provi'd'ed for each transfer member. Therefore, es there are eight of these members in a machine equipped with nine wheels, no transfer member being provided for the wheel of lowest' order) there are eight dogs, and as a wheel which has been carried and locked by one dog is advanced to the left by the movement of the computing carriage, its transfer member will move into engagement With the next dog' of the series. ment with which the transfer member has just moved, will, however, remain in its normal position, so that it will be disposed either before or behind the lug 94 of the transfer member which new moves 'into engagement with it, depending oi' course upon Whether or not said member is in its set or retracted position,A When the computing carriage is retracted, the transfer members 86,'moving therewith, will pass out of engagement with the dogs 92 and with the effective portion of the locking bar 90," so that when the lnumber wheels have been restored'to their normal positions at the right hand side of the casing 6, the transfer members will be unlocked, in order to permit the resetting thereof in position to :tg-.tin carry the Wheels.

The means fm1 resetting the transfer mechanism. The resetting of Vthe transfer mechanism is effected by power tlerived from the numeral keys of the typewriter, which, as .we have seen, operate the mast-or wheel locking arm 45 through intermediatoY connections.4 'lhe upper end of'the rtrm 45 hits a. loose pivot-ztl connection, ns indicated :it 95, with a tritnst'er meclntnism resetting lever 9b fulerumed intermedi-tte of its ends, as ih ndir-iited'at' 97, upon-.t 'fixed supper-LMS, Figs. 9 and l0'. The resetting lever 9(3is disposed opposite that arm 8o to which is connected the transfer member engaging the wheel located opposite the. notu- 'bitterl assuming the computing carriage to be in operative position.y The horizontal end 9) extends, however, o suiicient distance to the left to engage the next two -ztrms 8G, shown in Fig. l0. l

Aln order to clearly understand the manner in which the. resetting of the transfer mechnnism is effected, let it be assumed that the computing device has been opersted and that it has been retrocted'to the right hand" The dog out-of engage.

vanced into.proximity to the column, further movement of the carriage will advance the computing -device to dispose the number Wheel of highest-order in mesh with the master wheel or actuator 15. If now, a numeral key is depressed, the locking arm or detent 45 will be withdrawn from 'the actuator 1'5, thus simul taneously releasing the latter and swinging the resetting lever 96 from the position shown in full lines in Fig.' 9 to that shown in dotted lines in said figure.

l This movement of the resetting lever will swing 4forward that arm 86 which 4is'connectegl to the transfer member of the number wheel opposite the actuator, l the projection 83 on the'adjacent lockin'g'arm 78 dropping behind 'the head of the transfer memberand re- 'taining the same untilV elevated by one of the trip le vers 74i.i1 thersubsequent act 'of carrying when the- `transfer mechanismthus reset shall have movedxwith `its wheel to a position to the left of the actuator. As the resetting lever is provided with the horizontal end 99,' the described movement of the lever will not only effect'the resettingof that transfer member which is opposite the actuator, but will also simultaneously ef-4 feet the" resetting of the4 two-transfer members of next lower-order, the purposebeing to guard against failure `posed opposite the upper endy of the resetting lever during two or more actuations of4 the latter'. Oi course," if a-given transfer member is properly 'reset the first' time it is urged forward by theresetting lever, it will fnot beaffeeted by subsequent operations of the latter. If, however, for any reason, there should be a failure upon the' first throw, an opportunity or opportunities Iwill be' afforded for the proper resetting 'of the meme;4 ber -befoi'eit moves out'of 'cooperative relation with the 0 5 resetting lever and' before it moves in'to position to be utilized for carrying, thatfis to say, Abefore it moves to tho left 'of the'aetuzitor.` As the` computing carriage moves to the loft, the" transfer mechanisms will be" sucl lccssivelybrought opposite' the resetting lever, ,and

therefore 'all of said-mechanisms will be reset dui-ing' the advance of the '"carriage and' the resetting of each will occur inv-time topermitthe p roper performancejof i its function. l 'The forv locliitg the 'number whecls locatedvat 4tlie tn ec'hanis'nr serves to lock"'againstj`e ental`movelin'qint s u'ch .of the number wheels' es m the 1,efir`iff`theactuatonl The wheel inf with'the actuator will thef'rightofitheriictuator are locked. vLMountedto swing from the baril()l isa. nurxr Racking b ailglOO which 'extends entirely acrossth casiock'ngsange 10i. which exiendsfmiii the iightiigraines-i fiiiui sei-vingts semifinal e th-'Mtb fthe vlies!! and'tb look thesanie against acidentalmpvelnsntin "either-direction. i
